Bad communication skills
When my manuscript was first edited major spacing changes were made that I had to return to my original concept. Then the Production Department changed the font on all the Scripture references and reduced the size of my manuscript to 6x9, making no attempt to fix the abundant new spacing problems that this created. The manuscript was electronically returned as "read only" so I had to email an extensive list of corrections and hope that they would do them all. They did not, so this back and forth had to be done several times until I finally gave up in frustration, leaving a few small typos undone. Also, most of my questions went unanswered or I only received a pre-scripted computer generated response that did not address my issue.
